This paper studies the method of rationality evaluation of trip demand for urban citizens by using fuzzy logic theory. According to trip-demand time and space distribution characteristics of urban citizens, the peak-hour trip factor and saturation of road network were chosen as the evaluation indexes, meanwhile the index calculation formulas were given; then on the basis of fuzzy logic theory and index characteristics, the membership functions were established by using fuzzy logic toolbox of MATLAB, and the evaluation results of two indexes were analyzed; Finally, the evaluation process was illustrated by a case study of Yangzhou and the results indicated the validity and practicability of the method presented in this paper.

To study seismic behavior of new Tianjin library, a shaking table test of a 1/20 scale model is carried out for the main structure of the library. A steel frame-bracing system is employed in the main structure of the library. There are lots of removing columns and trusses with cantilevers in the interior structure with an irregular façade. Accordingly, this paper designs and products thoroughly the test model, including the selection of model material, the similitude-scaling relationship, the discussion for the model construction technology and design of test program. Finally, this paper lists the main result for the shaking table test.
